A study was conducted to develop a speaker verification system for use over a degraded channel such as a telephone line. A test of the current speaker verification technology was performed on a set of data which had been processed through the RADC Digital Communications Experiment facility (DICEF) to simulate a telephone channel. The simulated channel introduced an amplitude distortion, phase delay, and noise onto the analog data set. The noise did not present any particular problem other than...

The mean properties of the modified maximum entropy method (MEM) spectral estimator incorporating variable delay are developed for the case of a bandlimited (BL) complex signal in lowpass noise. Asymptotic cases of long filter length and degeneration to the white noise case are examined in detail. The modified MEM is shown to reproduce the input spectrum (to within a scaling factor) for delta = 1 and to provide a spectral whitening function as delta grows very large. Additionally, examples of...

The performance of an airborne laser terrain mapper, which collects slant range and reflectance data simultaneously, is determined in part by the spatial filtering effects of the finite laser beam spot size. An analysis of the spatial filtering effects and the resulting distortion of the terrain profile slant range to the aircraft is made to interpret the interaction between the terrain characteristics and the resulting laser line scan information. Emphasis is placed on the range interactions....

In this research, face recognition and speaker identification systems are each converted into verification systems. The two verification systems are then fused to form a single identity verification system. Finally, the use of the Karhunen-Loeve Transform (KLT) for dimensional reduction is examined for suitability in the verification task. The base face recognition system used the KLT for feature reduction and a back-propagation neural net for classification. Verification involved training a...

In this report we describe the development of a numerical solution technique for the simulation of high-speed multi-material impact. Of particular interest is the interaction of solid impactors with targets. Such interactions present the following challenges to numerical solution techniques: (1) high velocities of impact leading to large deformations of the impactor as well as the targets. (2) nonlinear wave-propagation and the development of shocks in the system. (3) Modeling of the...

In choosing a scheme for single mode fiber coupling, the final evaluation should of course be based on an experimental comparison between the alternative. However, such an evaluation will generally not reveal the essential limitations of any scheme. While the possible sources of less than ideal performance are well known, their relative significance is not so obvious. It is clear that in order to make significant improvements in the state of fiber coupling technology, the relevant limitations...

Noise-induced hearing loss acts as a low-pass filter for individuals receiving speech sounds or warning signals. These losses can also cause some degree of distortion in the auditory system, necessitating a speech-to-noise ratio of up to 10 dB more favorable to achieve speech recognition comparable to a normal-hearing listener. These distortions may appear in the frequency, intensity, and temporal domains. Hearing in the high-frequency range is important for understanding speech in noisy...

The offshore tide becomes distorted as it propagates into shallow inlet/estuarine systems. Time asymmetries develop in the rise and fall of sea surface with consequent time and magnitude asymmetries in tidal currents. Flood- dominant estuaries are characterized by longer falling tides and stronger flood currents while ebb-dominant estuaries have longer rising tides and stronger ebb currents. The asymmetries are reflected in the nonlinear growth of harmonics and compound tides of the principal...

Linear system identification of complex nonlinear systems, such as large space structures, can be difficult because such systems are often lightly damped, have dense modal spacing, respond to disturbances over a large frequency bandwidth, and exhibit nonlinear responses. Many excitation signals used to collect frequency response data for linear system identification are poorly suited to systems that exhibit nonlinear responses. Specifically, random noise, burst random noise, pulse-impact, and...

Investigating the effect of steam ingestion into an aircraft jet engine is necessary to improve understanding of stall and surge in transonic axial compressors. Specifically, to understand the pop stall phenomenon experienced by naval fighter jet aircraft during steam catapult launches. Steam leakage from an aircraft carrier catapult system can be ingested into the intake and cause stall or surge in a jet engine upon takeoff. It is important to understand the conditions under which this occurs...

Image quality assessment plays a major role in many image processing applications. Although much effort has been made in recent years towards the development of quantitative measures, the relevant literature does not include many papers that have produced accomplished results. Ideally, a useful measure should be easy to compute, independent of viewing distance, and able to quantify all types of image distortions. In this paper, we will compare three full-reference full-color image quality...

The statistical behavior of an idealized linear detector in the presence of threshold and saturation levels is examined. It is assumed that the noise is governed by the statistical fluctuations in the number of photons emitted by the source during an exposure. Since physical detectors cannot have infinite dynamic range, our model illustrates that all devices have non-linear regimes, particularly at high count rates. The primary effect is a decrease in the statistical variance about the mean...

This is a report on the continuation of our experimental investigations of the hypothesis of local isotropy in shear flows. This hypothesis, which states that at sufficiently high Reynolds numbers the small-scale structures of turbulent motions are independent of large-scale structures and mean deformations, has been used in theoretical studies of turbulence and computational methods such as large-eddy simulation. Since Kolmogorov proposed his theory, there have been many experiments, conducted...

This report presents a worst-case analysis of the EOS/AMSU-A (Earth Observing System/Advanced Microwave Sounding Unit-A) Antenna beam-pointing accuracy. There are three sources of beam pointing error. These are mechanical tolerances in the manufacture and assembly of the parts, allowable axial displacement of the reflector relative to the motor shaft, and on-orbit thermal distortions. For the worst-case analysis, each will be assumed to act independently and thus each contribution is additive.

The F/A-18A aircraft has experienced engine stalls at high angles-of-attack and yaw flight conditions which were outside of its flight envelope. Future aircraft may be designed to operate routinely in this flight regime. Therefore, it is essential that an understanding of the inlet flow field at these flight conditions be obtained. Due to the complex interactions of the fuselage and inlet flow fields, a study of the flow within the inlet must also include external effects. Full Navier-Stokes...
